The Jatikramat River (Kali Jatikramat or Kali Jati Kramat) is a river in Bekasi, West Java, and the eastern part of the Special Capital Region of Jakarta, Indonesia. [1] The lower portions of the original river have been channelized and directed into the eastern flood canal, "Banjir Kanal Timur", which continues to flow to the Java Sea in the district of Marunda, Cilincing, North Jakarta. [2] The river regularly causes flooding in the city of Bekasi [3] and Jakarta. [4]
The Jatikramat and the other two nearby rivers, the Cakung and Buaran, flow from Bekasi and interconnect until draining into the Jakarta Bay in the district of Marunda through Cakung Drain and currently through Banjir Kanal Timur. In the past, the three rivers supplied water for drinking and agriculture in the area. [5] Due to continuous erosion and accumulation of trash, the average width of the Jatikramat was reduced from 10 to only 3 meters in 1990. [6]
The river often causes flooding to the surrounding area. Research by Pieter J. Kunu and H. Lelolterry of Pattimura University, Ambon, showed that the development of the city changed 85% land of Jakarta to be waterproof, unable to absorb surface water and resulted in regular floods. One of the solutions was by constructing a flood-control canal, the Banjir Kanal Timur. [5] The flow of the Cakung, Buaran, Jati Kramat, Sunter, and Cipinang rivers was cut to drain into the canal, and thereby reducing the occurrence of flood. [5] However, one little part of the Jatikramat river is now still connected to the Buaran River at a length of almost 50 meters. [7]
The watershed of the Jatikramat in the city of Bekasi comprises the flow of the Cileungsi, Cikeas and Bekasi rivers. [3]
The Jatikramat river has a length of 14.50 kilometres (9.01 mi), with the watershed area (Indonesian : Daerah Pengaliran Sungai) of 16.50 km2. [8] The average daily rainfall is 154 mm, with the peak debit at 45 m³. [8]
The river flows in the northwest area of Java with predominantly tropical rainforest climate (designated as Af in the Köppen–Geiger climate classification). [9] The annual average temperature in the area is 28 °C. The warmest month is September, when the average temperature is around 31 °C, and the coldest is May, at 26 °C. [10] The average annual rainfall is 3674 mm. The wettest month is December, with an average of 456 mm rainfall, and the driest is September, with 87 mm rainfall. [11]
In early 2000, the flow of the Jati Kramat was straightened; the river was dredged and the banks were strengthened with concrete, to yield a width of 5 meter with the depth of more than 3 meter. [6] The normalisation in Pondok Kelapa, Duren Sawit, East Jakarta, was performed since 2015. [12] This normalisation resulted a width of around 10 meter, to control annual flooding. The project was to be completed until the river mouth at Kanal Banjir Timur (KBT). [13]
Ci Liwung is a 119 km long river in the northwestern region of Java where it flows through two provinces, West Java and the special region of Jakarta. The natural estuary of the Ciliwung river, known as the Kali Besar, was an important strategic point for trade in the precolonial and colonial periods and was instrumental in the founding of the port city of Jakarta, but has been lost from reorganization of the watercourse of the rivers around the area into canals.
Cakung is a district (kecamatan) of East Jakarta, Indonesia. The district is roughly bounded by Bekasi Raya Road to the west, the Bekasi Raya Road - Petukangan canal to the north, a portion of Cakung river to the east, and the Jakarta-Bandung-Surabaya railway to the south. A large area in Cakung is allotted to industrial or agricultural use. The Pulo Gadung industrial complex is located in the district. The district is served by Jakarta Outer Ring Road.
Cilincing is a historic neighborhood of the coast of Jakarta, Indonesia. It is sandwiched between the Port of Tanjung Priok to the west and River Titram to the east. Cilincing has been for some decades one of the districts of North Jakarta which in turn encompasses as far as Marunda and some non-coastal hinterland.
Flooding in Jakarta occurs on the northwest coast of Java, at the mouth of the Ciliwung River on Jakarta Bay, which is an inlet of the Java Sea and has happened recently in 1996, 1999, 2007, 2013, and 2020.
The Jakarta Flood Canal refers to two canals that divert floods from rivers around Jakarta instead of going through the city. This first flood control channel was designed by Hendrik van Breen, an engineer working for the Dutch East Indian Department van Burgelijke Openbare Werken, after a big flood hit the city on 13 February 1918.
The Angke River is a 91.25-kilometre (56.70 mi) long river in Jakarta, Indonesia. The river flows from Bogor area of West Java, passing through the cities of Tangerang (Banten) and Jakarta into the Java Sea via the Cengkareng Drain. The river is connected with Cisadane river by Mookervaart canal.
The Grogol River is a small river in the western part of the Special Capital Region of Jakarta, Indonesia. The lower portions of the original river have been channelized with levees built along its banks, but flooding remains a real concern. Illegal buildings built along its banks were removed in 2014, and fifty-eight village families were provided with replacement housing, but most of them could not be accommodated.
The Sunter River or Kali Sunter is a river that flows in the eastern part of Jakarta, Indonesia. The river is about 37 km long and has 73,184,092 m2 of river basin. Neighborhoods along the Kali Sunter are very densely populated and prone to frequent flooding.
The Madiun River is a river in East Java, Indonesia, about 500 km to the east of the capital Jakarta. It is the largest tributary of the Solo River. Its name indicates that it passes through the major city of Madiun, East Java, Indonesia. This river starts as a number of smaller tributaries converging near the city of Ponorogo, in particular the Kali Slahung, Kali Keyang and Kali Sungkur. It eventually converges with the Solo River near the city of Ngawi.
The Kambaniru River is a river in the island of Sumba, Indonesia, about 1,500 km east of the capital Jakarta. With a length of approximately 118 km, it flows periodically through 9 districts in the East Sumba Regency, exiting to the Bay of Kambaniru near the city of Waingapu to the Sawu Sea, with high debit in the wet season, but very low in the dry season.
The Mookervaart River is a canal connecting the Cisadane River in Tangerang and Kali Angke in Jakarta. Constructed from 1678 to 1689, this 25–30 meter wide channel is one of the important flood control water channels in Jakarta.
The Pesanggrahan River is a river with the upstream in the Bogor Regency, flowing through the cities of Depok, Jakarta and Tangerang, Banten. The river passes the districts of Tanah Sereal, Bojong Gede, Sawangan, Limo, Kebayoran Lama, Pesanggrahan, Kembangan, and Kebun Jeruk before flowing into the Cengkareng Drain. Based on 2005 data, 55 percent of the watershed area of the Pesanggrahan River is occupied by housing, only 7 percent is still forests, 20 percent rice fields, and 13 percent other agriculture fields.
The Krukut River is a river flowing in Jakarta originating in Bogor Regency. In the past the river was clean and one of the tourist attractions during the Dutch East Indies administration, but due to denser housing on the banks and lack of maintenance, the water turned dark and filled with trash, causing routine flooding in rainy seasons.
Cakung River is a river in the Bekasi, West Java and eastern part of the Special Capital Region of Jakarta, Indonesia. The lower portions of the original river have been channelized and directed into the eastern flood canal, "Banjir Kanal Timur", which continues to flow to the Java Sea in the district of Marunda, Cilincing, North Jakarta. The river regularly causes flooding in the city of Bekasi and Jakarta.
The Buaran River is a river flowing in the Bekasi, West Java and eastern part of the Special Capital Region of Jakarta, Indonesia. The lower portions of the original river have been channelized and directed into the eastern flood canal, "Banjir Kanal Timur", which continues to flow to the Java Sea in the district of Marunda, Cilincing, North Jakarta. The river regularly causes flooding in the city of Bekasi and Jakarta.
The Cipinang River is a river flowing in the Special Capital Region of Jakarta, Indonesia. Cipinang river is a tributary of Sunter River, conjoining near I Gusti Ngurah Rai Street and Cipinang Muara Ilir Street, Jakarta, but in the middle it is cut by the beginning of Banjir Kanal Timur, near Cipinang Besar Selatan Street dan IPN Street, Jakarta. The river flows mainly in the district of Makassar, East Jakarta, with many houses built on both banks.
Baru Timur River is a man-made canal flowing from Ci Liwung in Bogor Regency to Jakarta, Indonesia. It was one of two canals built in the 18th century under the order of the Governor-General Gustaaf Willem van Imhoff originally to transport agriculture harvest from Bogor to Batavia. Currently both canals, now known as Kali Baru Timur and Kali Baru Barat, are among the main rivers in Jakarta, and part of the Ciliwung Cisadane flood control project. Baru Timur River flows from Katulampa flood gate, built at the same time as the canal, along the major road Bogor Highway, passing Cimanggis, Depok, Cilangkap, until reaching Java Sea in Kali Besar, Tanjung Priok, North Jakarta.
The Baru Barat River is a man-made canal flowing from the Cisadane River in Bogor Regency to Jakarta, Indonesia. It was one of two canals built in the 18th century under the order of the Governor-General Gustaaf Willem van Imhoff, the other being the Baru Timur River. Both canals were originally built to transport agricultural harvests from Bogor to Batavia. They are among the main rivers in Jakarta, and part of the Ciliwung Cisadane flood control project. The Baru Barat River flows through the districts of Pancoran and Tebet in South Jakarta, and drains into the Banjir Kanal Barat.
Flash floods occurred throughout the Indonesian capital of Jakarta and its metropolitan area on the early hours of 1 January 2020, due to the overnight rain which dumped nearly 400 millimetres (15 in) of rainwater, causing the Ciliwung and Cisadane rivers to overflow. At least 66 people have been killed, and 60,000 displaced in the worst flooding in the area since 2007.
